The authors of this work has been published in ‘Proceedings of the National Academy of Sciences’, explained that these mammals live together in groups and need an effective system to keep in touch.
far been detected that dolphins talk to each other with whistles and there were indications that these names were like humans. However, this is the first time it is shown that there is a response to these whistles and, therefore, confirms the theory of names.
One of the researchers of this study, Vincent Janik, explained that to arrive at this conclusion, the team recorded a group of wild dolphins and captured the sound of ‘signature’ of each animal. They then used these calls playing them with underwater speakers. “We played with the whistling of the group of animals: we reproduced their own, others who were also emit other dolphin populations,” stated Janik, who has indicated that individuals only responded to their calls.
The team believes that dolphins are acting like humans: when they hear his name, they respond. Therefore, the scientist believes that the study of how communication has evolved from different animals could say more about how communication has evolved in humans.
